Abstract (en)
[origin: EP1312533A2] An electric motor (2) drives a pump (1) to supply an hydraulic reservoir (5) through a non-return valve (4). The reservoir supplies a brake (6), spring loaded to hold it off, and an electromagnetically operated proportional valve controlling the steering actuator (7). On failure of the motor provision is made to isolate the brake system from the reservoir.
